Mt Hamilton Lick Observatory: The University of California’s Lick Observatory has been in operation on the 4200-foot summit of Mount Hamilton, east of San Jose, California, since 1888. The Observatory is more than 20 miles from downtown San Jose along Mt. Hamilton Road.The road follows a gradual grade, which nowhere exceeds seven percent, laid out over a century ago for horses and carts. It has many sharp curves and is quite narrow in places.
